Alfredo Wiechers lived in his house for seven years. His works After leaving his architectural mark on the city of Ponce (Casa Serralles, Oppenheimer House) he sold his house to the Villaronga family and fled in 1919 to Barcelona, under political pressure. Although his prolific works (1911–1918) include hotels, stores, mausoleums, and even factories, the majority of his work was done in Ponce—he ventured out of Ponce only to design two structures for wealthy Catalan families in the neighboring mountain towns of Adjuntas and Aibonito. His work in Puerto Rico includes the designs for Logia Adelphia, Don Eugenio Serralles Residence (Casa Serrallés), the Oppenheimer House, and the Blasini Residence. He also designed the Club Deportivo de Ponce (Ponce Sports Club), the Vendrell House, and homes for the Gelpí and Arce families. Wiechers designed and built Casa Serrallés (not to be confused with Castillo Serrallés) in 1911. This commodious residence is located in downtown Ponce, at the southeast corner of Calle Isabel and Calle Salud and is currently home to the Museo de la Música Puertorriqueña. In 1911, Wiechers also designed the Mausoleo del Cuerpo de Bomberos of the City of Ponce (Mausoleum of the Corps of Firemen of the City of Ponce) located at the Cementerio Civil de Ponce on Calle Cementerio Civil in barrio Canas Urbano. He also designed Villa Julita also known as Casa Ulrich, a residence located in Aibonito, which is listed on the National Register of Historic Places. Later years and legacy In 1918 Wiechers returned with his family to Spain, claiming political persecution by the authorities in Puerto Rico. After this, he never performed as an architect again for health reasons as well as not being on possession of a license to practice architecture. He died on 15 July 1964, and was interred at the Montjuïc Cemetery in Barcelona at the Mausoleum of the Gilet family. He is honored at Ponce's Park of the Illustrious Ponce Citizens. The Architecture and Construction Archives at the University of Puerto Rico (AACUPR) is the custodian of the Alfredo Wiechers Collection (1896–1986). Approximately 1.5 cubic feet in size, the collection contains architectural drawings, photographs, and publications. The Architectural Drawings Series contains 128 projects organized chronologically. The collection was transferred from the Puerto Rico Architects Association in 1998. He also designed Quinta Vendrell, Barrio Portugués, located at the junction of PR-143 and PR-123, Adjuntas, Puerto Rico, which is listed on
